Today I got the Kaisheng DM7 and DM7Ti. I was so excited to unbox them that I forgot to take photos. Let me first say the conclusion: From what I heard, the quality of Kaisheng's DM7Ti is the ceiling of the new generation of flat-head earphones that surpasses the Titanium Bell Plus! Of course, the listening experience of the two is different. It is easier to hear the 7Ti on a portable device, the vocals are closer, the details are richer, especially in terms of analysis, sound field, and separation, which obviously surpass the Titanium Bell Plus. I haven't tried to compare the two on a desktop computer yet. I think the cheap DM7 is more like the successor of the Titanium Bell Plus style, and it is easier to drive. It is not an exaggeration to say that it is an easy-to-drive and flat replacement version of the Titanium Bell Plus. The limited edition and high-priced Titanium Bell cannot be bought, and buying the regular version of DM7 will definitely satisfy you.
Well, I admit that I am a HIFI guy. I have dabbled in desktop computers, speakers, big headphones, walkmans, and flat-head plugs, but my love for walkmans and flat-head plugs is engraved in my bones and lingering. Walkmans are portable and playable, and the sound quality is getting closer and closer to entry-level desktop devices. The domestic bricks have climbed to the top in terms of thrust, leaving Sony, iRiver and other foreign bricks far behind. Of course, the price is also rising. In-ear earplugs are the absolute mainstream at present, but for an old man who started with Aiwa V141, no matter how high-end the in-ear plugs are, they can't replace the loose and natural listening experience of flat-head plugs. Unfortunately, there are too few flat-head plugs in production, and even fewer that satisfy me. As a last resort, I can only look for old plugs that were once classics, but now the price is skyrocketing: V99, D9, HV100, 282, 484, V14, etc. Although it sounds convincing, the quality is indeed rare to reach the modern level. It wasn't until a few years ago that I heard the Titanium Bell Plus from Kaisheng at Dehai Jiye that I was amazed! And since they only make flat-head dynamic earphones, I have been determined to buy Kaisheng Plus, and the Titanium Bell Plus has also been my main earphone in recent years. After that, I bought DBX and X6 one after another, and I had different feelings when listening to them in turn.
Let's talk about the two protagonists this time: the latest DM7 and DM7Ti, the regular version is less than 1,000 yuan, and the titanium version is close to 6,000 yuan, which is definitely not cheap. The shape is similar to the classic CM7 of Audio-Technica. I don't know whether the sound is similar, but the quality is definitely improved across the century. In order to compare DM7, I took out DBX and Titanium Bell Plus, and chose the digital turntable V3-D and the decoding headphone amplifier TR-AMP in the front end for comparison under single-end. It can be said that the listening experience of the regular version of DM7 is excellent, which is what I think is the sound of fever reduction, and DBX is close to it in quality. As soon as I put on the titanium version of DM7, a huge amount of details and an expanded sound field came to my face. The singer's voice was like singing in my ear, and the sibilance control was just right, which made me unable to extricate myself. The dynamics were huge, mellow and slightly warm, strong, too strong. Then put on the Titanium Bell Plus, it was still majestic and balanced, but the high frequency seemed to be missing a part, and the details also needed a little effort to find. Comparing back and forth is tiring, but not boring. Many people don’t understand the hobby of HIFI guys, but in fact, it’s just for fun. . . . That’s all for now. There’s a long way to go. I hope more people will listen to this plug. Friends in Beijing can go to Dehai to try it out.
